Abstract

Shear bands were formed at room temperature in Zr44Ti11Cu10Ni10Be25 bulk metallic glass subjected to torsional deformation. Shear offset distribution was determined quantitatively for intersecting bands and compared to an elastic continuum shear defect model applied to similar band arrangements. The model reproduced the measured offset distribution, the residual stress field and different asymmetrical features of the band interaction. Differences between the model and the experimental results revealed the presence of a diffusion process for dilatational defects in shear band interaction.
